ENGINE DETAIL
The Avery 15-25 tractor, powered by a 4-cylinder gasoline engine with a displacement of 276.5 ci (4.5 L), exhibits a bore of 4.00 inches and a stroke of 5.00 inches, optimizing torque delivery for heavy-duty applications. Operating at a rated RPM of 1125, this tractor is designed for tasks requiring sustained low-end power rather than peak speed, making it suitable for plowing and towing in agricultural settings. However, its lower RPM may limit its adaptability for faster transport tasks, presenting a challenge in versatility compared to higher RPM tractors.

TRANSMISSION
The Avery 15-25 tractor features a simple gear configuration with 3 forward and 1 reverse gear, which enhances ease of operation for basic tasks but limits versatility in varied terrain and applications. This straightforward drivetrain design is ideal for users requiring reliability and ease of maintenance but may struggle with higher speed requirements or complex maneuvers. For optimal performance, it is best suited for flat, open fields or light agricultural activities where quick directional changes are less critical.

MECHANICAL
The Avery 15-25 tractor features a 4x2 two-wheel drive (2WD) chassis, which offers advantages in lighter weight and cost-effectiveness, making it suitable for small to medium agricultural applications. However, the 3-speed transmission may limit operational flexibility and speed adjustments compared to multi-speed alternatives, potentially constraining performance in varied terrain or heavy-duty tasks. Optimal scenarios include light tillage or transport tasks on flat, dry fields, where the simplicity and robustness of the system can be fully utilized.

AVERY 15-25 TIRES
The Avery 15-25 tractor equipped with 26x3 steel front wheels enhances stability and maneuverability, making it suitable for diverse agricultural tasks. The rear tracks provide superior traction and weight distribution on soft or uneven terrain, reducing soil compaction and enhancing field performance. However, the trade-off may involve increased wear on the tracks in hard soil conditions, limiting versatility across various environments.

DIMENSIONS & TIRES
The Avery 15-25 tractor's weight of 5,000 lbs (2268 kg) provides stability for various field operations, but may limit mobility on softer terrain. Its front tire size of 26x3 enhances steering responsiveness, while rear tracks improve traction and weight distribution, making it well-suited for cultivating and plowing on uneven ground. However, the trade-off with track systems includes increased maintenance and reduced speed on hard surfaces versus tire systems.
